between  the  brig  and  ishinds.  This  action  lias  caused  a  recession  of  the  main 
iloe:ourv,.ssel  has  changed  her  position  twenty  feet  within  tlie  last  two  sprin- 
tides,  and  the  hawser  connected  with  IJtifler  Island  parted  with  the  strain  "  The 
cutwater  of  th^-  brig  was  tlien  :iHO  feet  from  the  margin  of  the  ice  (Note  of 
J'l^bruary  itii.)  '  '     ^ 

The  mean  of  all  the  soundings  taken  during  the  fourth  s.'ries  is  very  nearly 
hfteen  feet,  hence  th.;  constant  index  error,  to  refer  the  observations  to  the  level 
previously  adopted,  is  eight  feet,  which  correction  was  applied,  comertin-  ut  the 
same  time  tlie  record  of  fathoms  into  feet.  "^

western const  of  Upper  (irecnland.  In  a  report  of  Mr.  .Soniita^f's  to  Dr.  Kane, 
dated  fiodhavn,  Sept.  12,  Ks.")."),  he  says:  The  mean  lieiij;ht  of  sjiriu;;-  tides  is  1'2.S 
feet,  and  at  the  tini(>  of  new  and  full  moon  high  water  is  at  !  ■.'''()";  the  highest 
spring  tide  is  fhrei!  days  after  full  moon,  an<l  the  night  tide  is  at  this  time  fidly 
three  feet  higher  than  the  day  fide.  At  Xorthumherland  Island,  Sept.  10,  llS.Vk 
at  (after)  the  time  of  full  moon  high  water  was  at  11''  P.  M.,  and  the  night  tide 
rose  three  feet  more  than  the  day  tide.  These  statements,  crude  as  they  necessarily 
arc,  show  that  the  attcTition  of  the  i>arty  was  fully  directed  to  the  phenomenon. 

.V  cursory  examination  ol'  the  Plates  il,  II,  and  111)  >iiows  thai  the  diurnal 
iniMpiality  extends  without  exception  o^'  '•  the  whole  series  of  oliservation.  that  it 
is  well  marked  in  the  dilfermce  of  tjw  iieight  of  high  water,  but  verv  little  or 
inci^'ulinly  in  tiie  height  of  low  water;  tjiat  sometimes  the  day  tide,  at  other  times 
tlie  iLJglit  tide  is  tile  higher  of  tile  two  occurring  in  a  lunar  day  ;  I'urther,  that  it 
\aiiishcs  a  day  or  two  after  the  moon's  crossing  the  iMpiator,  and  tliat  it  amounts 
in  maximo  to  about  three  feet  some  time  after  the  moon  attains  her  Ljreatesr 
declination.  There  i-  hut  oiii'  instance  where  tl;i'  iiiei|nality  approximates  to  the 
production  of  a  single  day  tide.     See  curve  for  Nov.  "J:!.  l>o;i. 

We  may  now  enter  sonu'wliat  more  fully  into  the  discussion  of  this  inequality, 
which  is  ju'oduceil  hy  the  interference  of  two  iiideiieiident  waves,  the  diurnal  and 
the  semi-diurnal,  the  former  depending  for  its  si/e  chietly  on  the  moon's  deilina- 
tion.  l''or  a  (omplcte  study  of  these  compound  waves,  they  re(piiri'  to  he  examined 
in  thi'ir  separate  parts,  and  it  wiuild  therefore  he  our  first  olijeet  to  ctl'ect  their 
separation  into  the  diurnal  ami  the  scmi-diiu'ual;  a  process  wjiich,  when  graphically 
performed,  is  neither  too  laborious  ncu'  lacking  m  accuracy;  it  is  nevertheless  a 
process  of  some  nicely,  and  reiiuires  observations  of  standard  cxccdlence.  I'pon 
trial,  1  found  the  less  rigorous  method  employed  by  ^Ir.  Whewell  in  his  discussion 
of  the  Plymouth  and  .Singapore  tides,  was  bi'tter  suited  to  the  general  mass  of  the 
observations  at  \'an  Ueiisselaer,  and  that  the  aliove  described  process  of  separatimi 
had  betti'r  be  reserved  to  tliat  portinii  nf  (Uir  olisei\atioiis  wliiih  are  apparently 
of  the  best  characti  r. 

Tiic  oliservi'd  heights  01  high  and  low  >vater  were  laid  down  graphically,  and  a 
line  was  drawn  b\  the  eve,  cutting  off  tin"  zig/ags  of  the  successive  high  waters,

The  diurnal  ine(|uality  in  time  I  have  tried  to  exhibit  by  numbers  as  well  as  by 
diagrams;  it  seems,  Ii(!\ve\('r,  that  the  incidental  irregularities  in  the  observations 
themselves,  cmipled  with  the  fact  that  the  oliservatinns  generally  were  only  made 
half-hourly  and  at  other  times  hourly — so  far  exceed  in  magnitude  the  ine(|uality 
itself  as  to  make  the  etlrct  nf  the  chanties  of  the  moon's  declinatiou  c  v.ceedint;ly

and  the  results  of  the  invest  illation  must  be  confined  '  i  the  following  general 
remark.  The  diurnid  iueipialit\  in  time'  is  in  nnixiina  probably  not  exceeding  t-wo 
hours;  it  seems  to  be  less  in  amoui  t  Ibr  the  tinu's  of  high  water  than  for  the  times 
of  low  water,  a  result  the  iCMrse  of  that  belnnging  to  the  ineepiality  in  height. 
A  similar  (onclusion  was  arri\ed  at  in  the  discussion  of  tin;  tides  at  San  I'rancisco, 
Cal.  (I'rof  A.  I).  IJache  in  Coast  Survey  Report  for  18.')3,  p.  *Sl),  wlu'ii  the  smiillfr 
incipialily  in  height  of  high  water  (when  coiniiared  with  that  for  low  water)  cor- 
responded to  the  (ffi'titi'r  inecpiality  in  time  of  high  water  (when  compared  with 
the  inequality  for  low  wati'r).  \\  hether  the  iiu'qualify  of  the  height  for  high  or
